INVENTOR DAVIS WEINSTOG'K, OF NEW YORK, N. Y.

FIRE-ESCAPE.

Specification of Letters Patent.

Patented Aug. 10, 1909.

Application filed February-2, 1909. Serial. No. 4375,551.

To all whom it may concern.

Be it known that 1, Davis XVEINSTOCK, a citizen of the United States, and residing at New York, in the county of New York'a-nd State of New York, have invented certain new and useful Improvements in Fire- Escapes, of which the following is a specification, such as will enable those skilled in the art to which it. appertains to make and use the same.

This. invention relates to .fire escape device or apparatus; and the object thereof is to provide an improved device of this class by means of which a party or parties may easily escape from the window of a burning building and descend safely to the ground; and with this object in view the invention consists in a device of the class specified constructed as hereinafter described and claimed.

The invention is fully disclosed in the fol lowing specification, of which the'aecompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a back view of my improved fire escape device, Fig. 2 a partial vertical section of the right hand side thereof, Fig. 3 a complete vertical section of the device taken in the same plane as the section shown in Fig. 2 but showing the parts in a different position, the section being on the line 33 of Fig. 5, Fig. 4 a view showing my improved fire escape device .in operation, Fig. 5 a side view of the device, and ;Fig. 6 a section on the line 66 of Fig. 3.

In the practice of my invention I provide a frame a which may be circular in form or approximately so, and to the bottom of which is secured a casing 19. The frame 00 consists of two similar members a between which is a space a and in the construction shown the casing Z) is also circular in form and the top portionthereof is beveled or conical in form, and the side members a of the frame a are separated and inclose the top portion of the casing b and are secured to the sides thereof as shown at a in Fig.5, and in the construction shown a plate a is placed on the top of the casing b, andthe end portions thereof are secured to the frame a at the opposite sides of said casing as shown at a and this plate forms a seat as hereinafter described.

Passing vertically through the casing 72 is a rotatable drum member 0 which is preferably tubular in form and to which is secured and onwhich is wound a rope (Z preferably composed of wire.

The separate'parts or side members a of the frame a are connected at intervals by transverse members, pins, bolts or similar devices 0, and to two of these devices the plate a is secured, in the form of construction shown, and on the right hand side of said frame, in the form of construction shown, these pins, bolts or similar devices 6 form supports for rollers f, and on said side of the frame a the said pins or bolts e are much closer than at the opposite side, and one of the pins or bolts 6 and one of the rollers f mounted thereon is in the central top portion of the frame a.

Mounted on one of the pins or bolts 6 at the bottom of the right hand side of the frame a and on which one of the rollers f is placed is a curved channel arm 9 provided with rollers 9 and the arm 9 is adapted to be moved toward and from the corresponding side of the frame a, and the casing 19 is provided with an aperture If, and the rope cl is passed out through said aperture and up and around the bottom roller f and inwardly of the otherr-ollers f and between said rollers and the rollers g in the channel arm 9, and

pivoted in the top of the right hand side of the frame a as shown at g is a dog h which passes down through a slot 71 and is provided at its free end with a transverse pin [i which limits the downward or outward movement of the arm g, and always holds said arm in position for use as hereinafter described.

In the form of construction shown there are three of the rollers g which operate in connection with the corresponding number of the rollers f, and the end of the rope d is provided, in the form of construction shown, with a hook 01 and in practice the "said end of the rope d is passed beneath the upper roller f in the top portion of the frame a and may be engaged with or connected with a hook or other support 6 secured at the top of a window of a building 1' as clearly indicated in Fig. 4.

In the bottom part of the drum 0 is a transverse pin 0 and I also provide a key device 7' for turning the drum 0 so as to wind the rope cl thereon. The key device j is in the form of a crank and is provided with a head j having a transverse recess j what I claim as new and desire to secure by adapted to receive the pin 0 and when it is desired to Wind the rope d on the drum 0 the head j of the key device j is inserted into the lower end of the drum and said drum is turned so as to wind the rope thereon.

The operation will bereadily understood from the foregoing description when taken in connection with the accompanying drawings and the following statement thereof. The dog it is provided on its under side edge with teeth It, and these teeth are adapted to engage the bottom edge of the slot 70 in the arm 9 so as to hold said arm 9 in such position as to clamp the rope d between the rollers and the rollers f, and with the parts in this position the device is suspended from the hook i as shown in Fig. 4. If, at any time, a party in the room or compartment 2' desires to escape from the window and descend to the ground the said party steps upon the window sill, the bottom sash being raised or both sashes knocked out, and the frame of the device is lowered so as to permit the said party to pass his feet therethrough and seat himself in the bottom of the frame a as clearly indicated at 00 in Fig. i, and by grasping the right hand side of the frame and the arm 9 in one hand and holding on to the top portion of the frame with the other hand or grasping the rope cl above the frame the said party can, aswill be understood, easily and quickly lower himself to the ground. In this operation the arm 9 is compressed or released so as to clamp the rope (Z between the rollers g and f and regulate the descent, and when one party has descended to the ground in this manner the device may be drawn up to the window and the rope re-wound on the drum 0 and another party may descend in the same manner.

The teeth h on the dog i are not absolutely necessary and may or may not be employed; and various other changes in and modifications of the construction herein described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention,
